Pressure Cycling Switch
A/C PRESSURE CYCLING SWITCHThe
A/C pressure cycling switch is closed when there is sufficient refrigerant charge. When the A/C control switch is turned "ON" and the
pressure cycling switch is closed, a request signal is sent to the ECM, which energizes the A/C control relay. When the ECM senses this signal it will also turn "ON" the cooling fan.
